Improved Auto-Resync Functionality
The existing auto-resync functionality on the IP Phones has been enhanced to reduce load on 
configuration servers. The following parameters for auto-sync have been added to the 
configuration file and the Aastra Web UI to support this feature:
•
The “auto resync max delay” parameter (in configuration file) and the “Maximum Delay” 
parameter (in the Aastra Web UI) which allows you to configure the maximum value for the 
random time the phone waits before beginning a download when the scheduled checksync 
occurs. Default is 15 minutes.
•
The “auto resync days” parameter (in the configuration file) and the “Days” parameter (in the 
Aastra Web UI) which allows you to specify the number of days the phone should wait after a 
checksync before trying the download again. Default is 0 days.
Setting these parameters can greatly reduce the load placed on the configuration server when 
downloading configurations.
